Speaking of which, do a fuel delivery test. The spec is 1000ml (1 liter) in 30 seconds. If it passes, then the SP is out of adjustment.

That’s what they were pushing on I believe.
Thank you so much for educating me. Just ordered a few things to get the fuel delivery test done this weekend. I did confirm that I just had a shop put a new fuel pump back in Oct of 2024 so I do not expect I will find an issue.
